2 nd December 2002James Magowan - Surrey e-Science Day32 e-Diamond - UK Digital Mammography Archive  “One of the pilot e-Science projects is to develop a digital mammography archive, together with an intelligent medical decision support system for breast cancer diagnosis and treatment. An individual hospital will not have supercomputing facilities, but through the Grid it could buy the time it needs. So the surgeon in the operating theatre will be able to pull up a high-resolution mammogram to identify exactly where the tumour can be found”  Tony Blair (speech to the Royal Society – 23 May 2002)
